2,3-Oxaphosphabicyclooct-5-ene-3-oxide derivatives with Et2N- or Mesityl NH groups on phosphorus undergo fragmentation readily when irradiated at -75 deg C in tetrahydrofuran.The solutions give 31P NMR signals at δ +12 and +9, respectively, which are attributed to solvated metaphosphoramidates (RR'N-PO2).These are rapidly converted to phosphoramidates (EtO-P(O)(OH)(NRR') on addition of ethanol.
